One-piece battery incorporating a circulating fluid type heat exchanger
First Claim
1. A one-piece battery comprising a tank divided into cells each receiving an electrode assembly, closure means for said tank and a circulating fluid heat exchanger facing relatively larger faces of said assembly, wherein said fluid flows in a compartment defined by two flanges, said compartment has a fluid inlet orifice communicating with a common inlet manifold and a fluid outlet orifice communicating with a common outlet manifold, said tank comprises at least two units, each unit comprises at least one of said cells delimited by at least one wall facing a relatively larger face of said assembly that constitutes one of said flanges, each unit further comprises a portion of said inlet manifold and said outlet manifold, and said units are fastened together so that said flanges when placed face-to-face form a sealed circulation compartment and said portions of the same manifold are aligned with each other.

Abstract
A one-piece battery comprises a tank divided into cells each receiving an electrode assembly, closure means for the tank and a circulating fluid type heat exchanger facing the relatively larger faces of the electrode assembly. The fluid flows in a compartment defined by two flanges which incorporate a fluid inlet orifice communicating with a common inlet manifold and a fluid outlet orifice communicating with a common outlet manifold. The tank comprises at least two units and each unit comprises at least one cell delimited by walls. The wall facing a relatively larger face of the electrode assembly constitutes one of the flanges. Each unit further incorporates a portion of an inlet and outlet manifold. The units are fastened together so that the flanges when placed face-to-face form a sealed circulation compartment and the portions of the same manifold are aligned with each other.
